  • Patent number: 5355162
    Abstract: A cable television system has a multiplicity of television program sources providing television signals in various predefined television signal formats. The program sources include continuous television sources provided to all users free of charge as well as pay-per-view program sources transmitted to users only upon request. Each television has a multi-standard receiver for receiving television signals in those predefined television signal formats, and is coupled to a transmission medium such as a coaxial cable. A television signal switch transmits the television signals from various ones of the program sources onto the transmission media in assigned respective frequency channels. Hidden behind each television, or elsewhere out of view of the user, is a converter coupling the respective television to the transmission media. The only connection from the converter to the television is a cable connected to the television's cable or antennae input port.
